Fall due to ice and snow (W00)

The ICD-10 code W00 covers falls caused by ice and snow, including detailed subcodes that describe the circumstances and timing of the fall. These codes document the type of fall; such as slipping on the same level, falling from stairs, or from one level to another; and specify whether it is the initial treatment, a follow-up, or long-term effects.

This section helps healthcare providers and coders accurately categorize injuries from winter-related falls. For example, if a patient experiences a slip on ice leading to a fall on a flat surface, the appropriate code might be W00.0XXA for an initial encounter. Synonyms like “fall on same level from slipping” or “fall due to slipping on ice or snow” clarify which code to use for various scenarios. Additionally, injuries from falls down stairs or other changes in level due to ice and snow have their own codes, such as W00.1 and W00.2. Unspecified falls on snow or ice are covered under W00.9, with subcodes distinguishing initial, subsequent, or sequela encounters. This granularity supports accurate medical documentation and proper injury classification.

Instructional Notations

Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

  • pedestrian on foot falling (slipping) on ice and snow

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • fall on from ice and snow involving pedestrian conveyance V00
  • fall from stairs and steps not due to ice and snow W10

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

  • The appropriate 7th character is to be added to each code from category W00

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela
